IMPROVEMENT IN FURNAOES.

Specification forming part of Letters Patent No. 28,2 I4, dated` May S, 1860.

To all whom it may concern.; r

Be it known that I, ROBERT R. TAYLOR, of Reading, Berks county,Pennsylvania,have inyented certain new and useful Improvements 1n the Construction of Furnaces; and I do herebydeclarethe following to be a fnll,clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of 'reference marked thereon.

My invention,which relates to the construction of puddling and other like furnaces, consists, first, in certain foundation-plates with retaining-ribs, certain side plates with vertical ribs, and bars with vertical recesses, the whole being arranged, adapted to each other, and ap plied to thc brick-work of the furnace substantiall y as described hereinafter, so that any one of the side plates may be removed without disturbing the others or the brick-work, and so that the said side plates may be free to expand independently of each other; secondly, 1n certain detachable plates adapted to the Openings for receiving the doors of the furnace in the manner describedhereinafter, so that they may be readily removed and replaced without disturbing the side plates; thirdly, inA a box carrying the ashpit door and connected to the foundation-plates by bolts, the whole being arranged as set forth hereinafter, for the purpose of maintaining the brick-work in front of the furnace entire.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure 1 is a side View of my improved furnace; Fig. 2, a longitudinal section; Fig, 3, a sectional plan; Fig. 4, a transverse section on the line 1 2, Fig. 1; Fig. 5, the same on the line 8 4; and Fig. 6, the same on the lines 5 6, Fig. 3.

Similar letters refer to similar parts throughout the several views.

A represents the foundation of the furnace, R the roof, a the bed, b the fine leading to the chimney, 'd the bridge, O the fire-place, and D the ash-pit, all of which are similar in form and arrangement to those of ordinary puddling-furnaces. In the foundation are built the two cast-iron plates G and G', which are connected together in frontin the peculiar manner described hereinafter, and which may be` connected at intermediate points by tie-rods e e,o r any other suitable attachments. On the opposite side'of the furnace are the plates f and f', h and h', j and j', kund k', and m and m', the lower ends of which rest against and are confined tothe side walls of the furnace by a ri b on the foundation-plates G and G', as seen in Figs. 4, 5, and 6. The edges of these side plates are furnished with projecting ribs, which lit into the vertical bars H-one of the ribs of each adjacent plate into the recess of one of the said vertical bars-fas best observed on reference to Fig. 3. The lower ends of each bar fit snugly into a recess formed in the foundation-plate, and the upper end of the opposite bars are connected together by the bolts l. The end plate, J, is connected to the opposite side plates, f and f', by vertical bars H, in a manner similar to that by which the side plates are connected together bythe same style of bars.

It is well known that the plates which hold together the walls of paddlingand other furnaces are apt to break by constant 'expansion and contraction, and that the substitution of new plates for the broken ones is a source of constant expenseand delay, as the Ordin ary method of securing the plates by bolts passing through their lower ends, as well as through the brickwork, involves the necessity of much fitting and adjusting, as well as the demolishing of the brick-work to a greater or less extent when a new plate is substituted for an injured one. It will be readily seen that these diiculties are obviated by the above-described improve ment, for should any one of the side plates be broken, all that is required is to loosen the vertical bars H which hold that plate, raise the bars from their sockets in the foundationplate, and after removing the broken side plate replacing it with a whole one, and finally restoring the vertical bars and tightening their bolts, all this being accomplished without any injury to the brick-work, and without displacing. the remaining plates. Moreover, the distance intervening between the edges of the 'adjacent plates, and the recesses of the bars being` suticiently large, the said bars offer no impediment to the free and independent expansion of each plate longitudinally,the plates being equally free to expand vertically.

Each of the plates h' ye" j has au opening furthe plates at this point.

nished with the usual sliding door, m, and la dinary furnaces form .ya part and are the rst to crackandbecomepseless thereby involving the inetsssiy ef ,renner,insl

the entire plate.

It will be seen, on reference to Il, 'th-afi j each side plate which hasall :Qpening :and .(1991 is. furnished with lugs a: x, wh' h are inclined (at the top) downward toward ith@ side plate, as seen in Fig. 4. Each p separate casting, has an in under side adapted to the inclination .on the top ofthe lugs x, so that'each plate et 'be moved,when broken or otherwised .ter and replaced with a new one Without the 1119- cessity of destroying the entire side plate to which it is connected.

In all puddling-fnrnaces the brckfwork at the front end is the first to become displaced, hence the importance of a proper retention of 1Itwill be seen, on reference to Figs. 2 and 6, that the ash-pit door is hung to a box, K, built into the brick-work, independent of the end plate, and that this box is connected by bolts q q to the foundation-plates G and G', so that there is no possibility of any outward l te t., which .is a ed rib en the rated,

movement of the said plates taking place. 1'lhe'briek-work in front ofthe furnace is thus securely confined, and the end plate, J, and box K are allowed a free and independentexpansion and contraction.

,I-claim as my invention,and desire to seeure by Letters Patent- The foundation-plates G and G' with their ;1:et ai;ningribs, the'side plates of the furnace with the vertical ribs, and the bars H with their vertical recesses, the whole being ar- Vranged and' adapted to each other and applied to .the brick-work `of a furnace substantially and nfor the purpose s et forth.

2, 'The `detachable plates n', adapted to the lugs ,fr :on the side plates, and arranged in respect to the 4openings on the same in the manner .and ,for the purpose specified.

.3.- Tlle 'box K, carrying the ash-pit door, and

` connected to the foundation-plates G and G by bolts g q, the whole being arranged as set forth, vfor vthe purpose specified.

In testimony whereof Ihave signed my name to this .specification in the presence of two subscribing witnesses.
